        <pre class="source-code cpp">

        <h3>Description</h3>
        <p><span>This function replaces the contents</span> <span>of the element at `pos` with the</span>
<span>specified param.</span></p>

<p><span></span>
<span>All iterators that are equal to</span>
<span>`pos` or come after are invalidated.</span></p>

<h3>Example</h3>
<code>
url u( "?first=John&last=Doe" );

u.params().replace( u.params().begin(), { "title", "Mr" });

assert( u.encoded_query() == "title=Mr&last=Doe" );
</code>
<h3>Complexity</h3>
<p><span>Linear in `this->url().encoded_query().size()`.</span></p>

<h3>Exception Safety</h3>
<p><span>Strong guarantee.</span>
<span>Calls to allocate may throw.</span></p>
